Entanglement-questions photons

[itoero]

Photons contain kinetic energy. When you entangle photons, do you change the properties of the kinetic energy which forms the wave energy? Kinetic energy is proportional to temperature...

Kinetic energy is also proportional to relativistic mass.(in Special Relativity) So is the mass of entangled photons defined by the kinetic energy of the photons or photon before they got entangled? (conservation of mass/energy)

The conservation rules apply for entangled systems just as they do for individual particles. If you knew the total input momentum with little uncertainty, then you would know the entangled system's total momentum with little uncertainty.
